Wow, Sergh, I am impressed !

~/= : up to 100/1 ratio
" physiologically " : soft facts area , could be or not could be
wristify,EMBR lab : low input / great output " feelings"
https://embrlabs.com/ Our body has receptors, but the sensivity is between the several bodies not the same
Genetical,habit ( for an Inuit 0° C is relatvely " spring " ambient) :
climate-chamber ( - 100 ° Celsius ) and thermografic camera body controle
Science wants hard facts !
Repeat-/ controle-ability
Not : " it seems that ..... !"( from physics to physio- to psycho to

PSI to mental insanity )
Physiologically :
a 20 sqm room equipped with 1600 W heater before, later 400 W heater ( Leo Peron) and finally 40 W heat foils ( Dr. Helmut Reichelt, IR room object heating) to 12 W electric body wear
Also : 100/1 Wattpeak/ Wattdeep ratio
Haus-/House-Raum/room or Weltraum/"Space" or body climatization
Your criticism and the KAPAGEN tests result : 34 Lumen/ Watt ~ CFL efficiency , does this result and method satisfy you ?
What was Naudins' target and what is your experimental result target. ?
You can have the world best hardware,
but have you also the best " software" and the before/after-vision target/ intention ?
Let us beginning with : halogen lamp lightning efficiency ( without controller)
https://www.any-lamp.com/lumen-to-watt in average 10 lumen/ Watt
Definition and relationship :
lux and lumen and Watt and VA and Photon and Phonon and Electron
https://en.m.wikipedia.org/wiki/Heat_transfer_physicshttps://www.any-lamp.com/blog/lumen-and-lux/About " halogen lamps can not flash fast"
http://www.electronics-lab.com/project/pwm-halogen-lamp-dimmer/ PWM IS FLASHING : energy flashing
And cause the "transformer" in future will become printed :
energy transformer: energy prozessor- equivalence
we can transform the termination circuit signals/ pulses per second now to flops per second :
https://en.m.wikipedia.org/wiki/FLOPSThe GFLOPS and TFLOPS price list from 1961 to today and this translating in printed "ambiental energy harvester"KWp/Wp future prices development and as product : KWh power costs decrease
The thin-foil-printer velocity will in future dictate the world energy market price and the consumer access.
